What is chemical equilibrium? |
|
Definition
the state in which forward and reverse reactions balance each other because they occur at equal rates |
|
|
Term
What is equilibrium constant? |
|
Definition
Keq is the numerical value that describes the ratio of product concentration to reactant concentrations, with each raised to the power ocrresponding to its coefficient in the balanced equation |
|
|
Term
What is heterogeneous equilibrium? |
|
Definition
a state of equilibrium taht occurs when the reactants and products of a reaction are present in more than one physical state |
|
|
Term
What is homogeneous equilibrium? |
|
Definition
a state of equilibrium that occurs when all the reactants and products of a reaction are in the same physical state |
|
|
Term
What is the law of chemical equilibruim? |
|
Definition
states that at a given temperature, a chemical system may reach a state in which a particular ratio of reactant and product concentrations has a constant value |
|
|
Term
What is a reversible reaction? |
|
Definition
a reactoin that can take place in both the forward and reverse directions; leads to an equilibrium state where the forward and reverse reactions occur at equal rates andthe concentrations of reactants and products remain constant |
|
|
Term
What is Le Chatelier's principle? |
|
Definition
States that if a stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress |
|
|
Term

Term
What does the equilibrium do if you add reactants? |
|
Definition
|
|
Term
What happens if you remove products? |
|
Definition
the equilibrium shifts to the right and more products are produced |
|
|
Term
What happens if you add products? |
|
Definition
equilibrium will shift to the left |
|
|
Term
What will happen if you decrease the volume? |
|
Definition
increased presure will cause the reaction to shift in the direction of the fewer gas particles |
|
|
Term
